Tweening Colors on Spark AR via Script

问题 what would be the equivalent of a transition Patch in Reactive script? I would like to tween a color from say 0,0,0,1 to 1,1,1,1 in RGBA. I know ho to animate a single value as alpha, like this: const timeDriver = Animation.timeDriver(timeDriverParameters); const alphaSampler = Animation.samplers.linear(1, 0); const alphaAnimation = Animation.animate(timeDriver, alphaSampler); mymaterial.opacity = alphaAnimation; Using visual patches you can use a Transform Patch to link a Vector3 to an

问题 Is it possible to have reactive SCS application using functional ( spring.cloud.function ) style with multiple, separate functions / bindings? All examples I have found always register only one functional bean with default bindings input, output . I would like to register multiple, each with its own bindings. Traditionally this could be done using spring-cloud-stream-reactive but it is now deprecated in favor of functional support. 回答1: Yes, it is possible in the latest snapshot and we'll be

问题 I would like to add buttons to my DT (one for each row - in first column). When I click on the button it should remove the row from DT. I wrote a code: library(shiny) library(DT) shinyApp( ui <- fluidPage(DT::dataTableOutput("data")), server <- function(input, output) { values <- reactiveValues(data = NULL) values$data <- as.data.frame( cbind(c("a", "d", "b", "c", "e", "f"), c(1463, 159, 54, 52, 52, 220), c(0.7315, 0.0795, 0.027, 0.026, 0.026, 0.11) ) ) shinyInput <- function(FUN, len, id, ..

RxSwift Shared Subscription Execution Order

问题 How can I ensure that a subscriber to an Observable will receive the onNext event after another subscriber? My example is the following: let firstNameObservable = firstName.asObservable().shareReplay(1) let lastNameObservable = lastName.asObservable().shareReplay(1) let bioObservable = bio.asObservable().shareReplay(1) let websiteObservable = website.asObservable().shareReplay(1) firstNameObservable.subscribe(onNext: { [unowned self] firstName in self.accountDetails.firstName = firstName })
